I recently just finished a book by G.K. Chesterton called Orthodoxy. It is basically a testimony/his reasons for rational believing in Christianity. It is deep, eloquent, philosophical, and mostly way over my head.
Here is a passage from near the end of the book where he is responding to people who think of Jesus as being passive and un-exciting.
"Instead of looking at books and pictures about the New Testament I looked at the New Testament. There I found an account, not in the least of a person with his hair parted in the middle or his hands clasped in appeal, but of an extraordinary being with lips of thunder and acts of lurid decision, flinging down tables, casting out devils, passing with the wild secrecy of the wind from mountain isolation to a sort of dreadful demagogy; a being who often acted like an angry god-- and always like a God. Christ has a literary style of his own, not to be found, I think, elsewhere; it consists of an almost furious us of the "a fortiori" (I have no idea what that is). His "so much more" is piled upon another like castle upon castle in the clouds. The diction used about christ has been, perhaps wisely, sweet and submissive. But the diction used by Christ is quite curiously gigantesque; it is full of camels leaping through needles and mountains hurled into the sea." ....."The one explanation of the Gospel language that does explain it, is that it is the survey of one who from some supernatural height beholds some more startling synthesis." -G.K. Chesterton
